COMBINED TROLLEY HEAD AND WHEEL.

SPECIFIQATION forming part of Letters Patent No. 539,798, dated. May 28,1895.

Application filed October 11,1894- Serial No, 525,580. (No model.)

To all whom it may concern: 7

Be it known that 1, WILLIAM H. DALBEY, a citizen of the United States,residing at Indianapolisfin the county of Marion and State of Indiana,have invented a new and useful Improvement in a Com bi ned Trolley Headand Wheel, of which the following isa specification.

My invention relates to new and useful im-.

provements in combined trolley-heads and wheels of the class used onelectric railways employing an overhead wire for the transmission of theelectric current.

The objects of my invention are to provide a combined trolley-head andwheel that will be strong and durable, that can be easily repaired incase of breakage, and means for continuously supplying lubricant to thejournal of the wheel. Iattain these objects by means of theconstructions shown in the accompanying drawings and described in thefollowing specification.

In the drawings which are made a part hereof, similar letters ofreference designate similar parts throughout the several views.

Figure l is a perspective View of my combined trolley head and wheel;Fig. 2 is a vertical sectional view of the wheel and bushing with thejournal in the bushing. Fig. 3 is a view of the inside of one of thesections of the head, slightly in perspective. Fig. 4 is a perspectiveview of the end of the trolley-arm forming a part of the head. Fig. 5 isa perspective view of the journal-bushing.

Referring to the details of the drawings, A, designates the trolleywheel; B, the easings forming the head; 0, the end of the trolley arm;D, the journal bushing, and E the journal.

The wheel A, is hollow and is provided with the opening 0, through whicha suitable lubricant maybe inserted into the chamber h. The bushing D,fitted within the wheel is provided with suitable openings i, throughwhich the lubricant j, will gradually diffuse itself upon the journal E.The ends of the journal E, extend slightly beyond the bushing D, saidends being slightly tapered and squared as at k, to fit into like shapedapertures Z, in the two casings B. The inside of the casings or sectionsB, forming the head, are constructed with angular grooves m, saidgrooves being ofa depth equal to one-half their width. At the upper endof the said angular grooves m, are rectangular openings 4%, saidopeningsbeing as long as the width of the angular grooves m, and the lower edgeof the openings coinciding with the bottoms of the grooves m, thusforming a substantial continuation of the grooves m, at their bottoms,but leaving a portion p, at the upper ends of the grooves 111-, thusforming a connection between the upper edges of said grooves. Thesections B, are also provided with openings .3, through which the bolt0", is adapted to pass. The end of the trolley arm 0, is squaredat itsupper end for a sufficient distance to fit within the angular grooves m,and has the-slot 15, cut across the upper end, of a sufficient depth andwidth to allow the two portions 19, of the sections B, to fit snuglywithin the slot 2%. The arm G, is also provided with the openingo, andthrough which the boltr, is adapted to pass. 1

It will be seen that the sections B, can be quickly laid together withthe Wheel A, in place between, and the end of the-trolley arm0,.inserted in thesquare opening,jfor'med by the angular grooves m, andpressed upward until the rectangular ends to, of the arm 0, enter therectangular openings n, of the sections B, thus binding said sectionsfirmly together. Surrounding the apertures Z, on the inner faces of thesections B, are circular boxes as, which are adapted to fit over andagainst the hubs g, on the wheel A, thus 'makinga continuous connectionbetween the head and the wheel for the passage of the electric current.The bolt 0", is then inserted through the openings .9, and o, of thesections B, and arm 0, and thus prevent the withdrawal of said arm, and,at the same time, gives additional strength to the various parts bybinding them together more firmly. The journal E, is held againstturning by means of the squared ends is, which fit in the squaredapertures Z, in the sections B. A sufficient quantity of lubricant maybe inserted into the chamber h, through the opening 0, to thoroughlylubricate the bearing for along period of time, as the openings z', inthe bushing D, may be made of a size and shape to admit only the amountof lubricant necessary to properly lubricate the journal E. I preferably use as a lubricant graphite dust, but do not confine myselfexclusively to such lubricant.

It is obvious that a combined trolley-head and Wheel constructed asabove described, will require very little attention for any purposewhile in use, and in case of breakage, any part can be quickly replacedby the trainmen Without being taken to the shop, thus preventingannoying delays to passengers, and loss to the owners.

Having described my invention, what I claim, and desire to secure byLetters Patent of theUnited States, is-

1. In a combined trolley-head and Wheel, the combination of the Wheel A,having the lubricating chamber h, and the hubs y, the bushing D, havingsuitable openings i, and the journal E, having the squared ends 70, withthe head sections B, having the squared apertures l, the circular boxes00, the angular grooves m, the rectangular openings n, the

connecting portions cl, the circular openings 8, and the arm end 0,having the slot t, the rectangular ends w, and the opening '0, allsubstantially as set forth.

2. In a combined trolley-head and wheel, the combination with the headsections B, having angular grooves m, and rectangular openings 1;, ofthe arm end 0, having the rectangular projections w, on the end thereof,for the purpose shown and described.

3. In a combined trolley-head and wheel, the combination of the journalE, having tapering ends 7a, with the head sections B, having taperingapertures Z, adapted to receive the ends of the journal E, substantiallyas shown and set forth.

In testimony whereof I have hereunto set my hand in the presence of twowitnesses.
